Abstract

Tests were done measuring resistivity and time domain induced polarisation using standard multi-core cable spreads and a special layout with separate cable spreads for transmitting current and measuring potentials. For both types of cables spreads both normal and reciprocal measurements were done in order to estimate the measurement errors. The tests were done on a former landfill in Lund in Sweden. The electrode contact was favourable with resistances of some hundred ohm. The results gave low average error levels for both types of cable spreads, but the single cable spread showed a larger variation with more scatter in the IP data. Data for both types of spreads gave very consistent models that delineate the lateral distribution of waste as well as the contaminant leachate flow path. The results agree well with observations of contaminant outflow and test pit results. It is concluded that the standard approach with a single cable spread is adequate for a site with favourable characteristics as the one studied here.
